Procedure
To a stirred mixture of methyl-2-tert-butoxycarbonylamino-3-(3,5-dibromo-4-hydroxyphenyl) propionate (0.20 g, 0.44 mmol), potassium carbonate (0.15 g, 1.1 mmol) and acetone (15 mL) was added 3-trifluormethyl benzylbromide (0.26 g, 1.1 mmol). The procedure followed was the same as described in Example 1, but the isolation on column chromatography of the intermediate methyl-2-tert-butoxycarbonylamino-3-[3,5-dibromo-4-(3-trifluormethylbenzyloxy)phenyl]propionic acid was not done. Purification of the final residue by HPLC, using the same conditions as described in Example 1(b), gave 20 mg (9%) of 2-amino-3-[3,5-dibromo-4-(3-trifluormethylbenzyloxy)phenyl]propionic acid. LC-MS (electrospray): m/z 498 (M+1).
